CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No.201711476674.9 entitled DEVICE FOR REMOVING TOOL JOINT EDGE BURRS FROMCAP OPENING OF WHEEL filed Dec. 29, 2017, which is incorporated hereinby reference for all purposes.

FIELD OF THE INVENTION

The present invention relates to the technical field of burr removal,and specifically, to a device for removing cap opening burrs from awheel.

BACKGROUND ART

A wheel is machined by first turning and then second turning. A tool iswithdrawn from a tool withdrawal groove after a center hole is completedby first turning, a tool is withdrawn along an oblique chamfer of a capopening after the cap opening is completed by second turning, a ring ofburrs appears at the joint of the both, and the burrs located inside thenarrow cap opening are very difficult to remove. The burrs are mostlymanually removed at present, so that the internal area of the capopening is easily scratched; and the burrs are not removed uniformly,which easily results in corrosion failure. On the basis of the currentsituation, the present patent designed a device for automaticallyremoving burrs from a first and second tool joint inside a cap openingwith high precision. The device can eliminate the influence ofcoaxiality deviation of first and second turning on the burr removingeffect, so the device has very high machining precision and can be usedfor automatic continuous production.
